Usually if it does this it means the belt is still not tight enough. After starting, the alternator puts out its maximum charge rate briefly, then settles down as the battery voltage comes back up. You might need to have the belt tightened again, because a new belt will sometimes stretch a little.

It also helps if you make sure that all power-hungry accessories are turned off before you start. Heater fan, wipers, radio, lights, etc. If these come on when you start up they add to the load. It varies with vehicle and circumstances, but some cars will squeal no matter how well adjusted the belts are, if there are a bunch of accessories on when they crank.

Could be the idler pully, mine squeeks on rare occasions....and you'd have to open the hood to really notice it.
